Right atrial tumor embolism from thoracic chondrosarcoma: A case report.

Chondrosarcoma accounts for ~15% of all primary malignant bone tumors. Chondrosarcoma of the spine is rare, while intra-atrial tumor embolisms as a result of chondrosarcoma are extremely rare. In the present study, the case of a 70-year-old male with thoracic chondrosarcoma, who presented with a fever and exertional dyspnea, is reported. Following anti-infection treatment with cefoperazone sodium and sulbactam sodium, the patient developed shock and a mass was identified in the right atrium by echocardiogram. The patient subsequently developed acute circular breathing failure and succumbed to the disease. To the best of our knowledge, this is the first case of thoracic chondrosarcoma with a tumor embolism in the right atrium to be reported in the literature.
